PAD PROPELLANTS FOR USE AT HIGH TEMPERATURES. PART II - EXPOSURE OF NITRATE ESTER PROPELLANTS TO HIGH TEMPERATURES, AND BALLISTIC FEASIBILITY OF COMPOSITE PROPELLANTS IN PAD CARTRIDGES

Abstract

Single and double base propellants, as used in propellant actuated device (PAD) cartridges, were subjected to high temperature conditions short of autoignition. Their thermal deterioration was measured by decay in peak pressures in firings in the M-73 PAD Cartridge/M-3 Initiator system and by estimation of weight loss, change in nitrogen content of nitrocellulose, gas evolution, and grain deformation. The propellants degraded rapidly at 225 and 250 F, and would not survive 275 F for evaluation. The ballistic feasibility of substituting composite propellants for nitrate esters in PAD cartridges was demonstrated in the M-73 cartridge. Composite propellants employing ammonium perchlorate oxidizer performed satisfactorily in the M-73 Cartridge/M-3 Initiator system at -65 F, but were marginal after two hours' exposure at 400 F.
